<pre>Clang OpenMP support is undocumented:
- the OpenMP command line options that clang supports are not documented, e.g.,
see <a href="https://clang.llvm.org/docs/search.html?q=openmp">https://clang.llvm.org/docs/search.html?q=openmp</a>
- there isn't a section in the documentation about using OpenMP with clang.
There should be such a section that shows how to compile an OpenMP hello world
program with clang using both llvm's and gnu's openmp run-times.
- the documentation section should point out to the openmp.llvm.org docs, which
should show how to build the openmp-rt library with clang in tree such that it
gets picked up by default when a user runs clang -fopenmp
- the documentation section in openmp.llvm.orgs should be expanded to show how
to use the library with clang when e.g. doing an out-of-tree build of the
library, and also how to build the library in-tree such that the systems
default is picked instead by clang by default.</pre>
